Simple NFC Reader for Android

Simple NFC reader for Android based on the sample code from the Android SDK.

If you have problem compiling the app make sure you have the /libs/guavalib.jar included in the build path.

nfc-reader's Issues

Save tag information

???

The ability to ignore some ids

Sort of related to #18 but in my case I have a phone case with a wallet that gets scanned if i fold the case out too close to the phone.

"Clear all" does not appear to clear tag data/contents

I discovered this when playing with some NFC tags on a Samsung S10E. In short, a simple unlocked NFC tag containing a youtube link was scanned with the app a few times. when trying to clear them, they didn't seem to clear.

1. download the NFC tools app
2. write a youtube link to an NFC tag (i don't have the tag with me right now but it seemed to be a fairly basic ISO type tag as shown by nfc tools)
3. scan the tag with this NFC reader app (v0.15) one or a few times
4. click the "clear all" button

Expected Behavior: the youtube links scanned from the tag should disappear from the app
Actual Behavior: They do not disappear from the app

Apologies in advance for the lack of some details. Its also entirely possible that this might be user error so don't sweat it too much if its not reproducible

Does not give card details, only ID

Card reader does not give the card details, it only shows a tag id. Can you please tell me how to solve this issue?

wrong tag type detected

the reader shows a NTAG203 as Mifare Ultralight C

Feature request: Only scan when app is open

If I set the phone down on a library book (really, just holding it near), the app opens and interrupts anything else I'm doing. For example, reading a book in one hand, streaming a video on my phone in the other, and when my phone got near the book it read the NFC tag in the book and cut off the video.

Please enable a setting to only scan when the app is open with primary focus, or just set that by default.

Regarding nfc reader application run issue

Adaptive icon

I'd really like to see an adaptive launcher icon for this app. Adaptive icons were introduced in Android 8: https://developer.android.com/guide/practices/ui_guidelines/icon_design_adaptive

How to write profile change vibration mode tag to nfc tag

Many folders are missing in the zip-folder

Hello,
I've just downloaded the zip-file and compiled it but then there are everywhere errors and I think it's only because of the imports of some folders which aren't in the download-zip-file:

import se.anyro.nfc_reader.R;

import android.app.Activity;
import android.app.AlertDialog;
import android.app.PendingIntent;
import android.content.DialogInterface;
import android.content.Intent;
import android.nfc.NdefMessage;
import android.nfc.NdefRecord;
import android.nfc.NfcAdapter;
import android.nfc.Tag;
import android.nfc.tech.MifareClassic;
import android.nfc.tech.MifareUltralight;
import android.os.Bundle;
import android.os.Parcelable;
import android.provider.Settings;
import android.view.LayoutInflater;
import android.widget.LinearLayout;
import android.widget.TextView;

All those and some others aren't possible to import because the folder is missing, or am I wrong?

best regards,
Robert

Crashes on phone without NFC

Please fix that

Unable to scan certain tags on the app

Issue:
I am unable able to scan some tags as it is not supported by the app. But I was able to scan them with NXP's TagInfo. Is there anyway to fix this issue as I just want the UID from the tag itself.

Screenshots of one of the tag's:

Compilation.Closed. I found in issue 4.

Hi,

mTagContent = (LinearLayout) findViewById(R.id.list);

Wrong settings screen displayed on Android 8 to enable NFC

When NFC is not enabled, the app launches the network settings screen to enable it.
But on Android 8, it's enabled on the "connected devices" screen.

My phone: Nexus 5x running Android 8

Thanks for the app!

Convert to Library

Hi Adam,

Thanks for sharing the code of your app. It makes an excellent case study. I am planning to fork your code and refactor it slightly so that it can be used as a Library. Mainly I will be changing getView to getRecord.

I will give you full credit. I just wanted to check with you a couple of things:

1. Do you see it as a complete solution and if not what features are missing? I will add these to the backlog.
2. Would you prefer the repository was hosted on your account so that you get full credit and I am just a contributor?

Thanks from one Adam to another,
Adam.

background gone dark

one of the last updates - my S8 now has the background in a very dark colour and its hard to read the tag details - email and contact info highlighted - just nothing else

Can't read from OnePlus 3

Not important to me personally.

However I tried your app on my OnePlus 3T with a NFC tag that I know I can read from other apps on the same device. And nothing happens.

Wrong data scanned

NFC tag after scaning shows this :

80 58 99 9a 91 84 04
ID (reversed hex): 04 84 91 9a 99 58 80
ID (dec): 36126213765432324
ID (reversed dec): 1271660805707904
Technologies: NfcA, MifareUltralight, Ndef
Mifare Ultralight type: Ultralight C

Licensing terms

I can't find any licensing terms with the source code. Does this mean you release it to the public domain? Or do any other terms apply?
when in doubt, go with Apache License 2.0 please :)

I am trying to read values from ez-link Singapore MRT card. Below image is my current output:

How fetch values like travel history/ current balance, refer below image:

Source code did not contain R.java and BuildConfig.java in your source package !

as title.

I download source package and try to build, but it complained. I search all over your commit check-in, and I cannot find those two files R.java and BuildConfig.java. Can you please also check in those two files ?

Those two files were generated automatically, but without those two files, it cannot be compiled successfully in Windows Eclipse IDE environment. Please provide it to me. Thanks.

Forward the raw data to a port on the phone

hi,
There is a very good usecase for using the phone's NFC reader on the desktop by connecting it with ADB and running a portforward.

For example, on the phone you could do

echo Just testing' | nc -l -p 1112 #putting it on port 1112

on the desktop,
do a port forward "adb tcp:1111 tcp:1112"
read the data from port 1111 - nc 127.0.0.1 1111

Not only this, you could now get desktop apps to read from the forwarded port and have access to the NFC scan data.

Could you add a feature to push NFC scan raw data to a port on android - you can hardcode this.

thanks!

Broken Google Play Store link

The link of the "Get it on Google Play" returns a 404 error on Google Play's website.
I also couldn't find the app by searching for it on the play store.
